To ell whom it may concern:

Be it known that l, lecon L. STOFFER, e citizen ot' the vUnited States, residing et Homeworth, in the county of Colombiano end State otloio', lieve invented certain new end useful .improvements in Bolt-Locking Bef Vices, oli which the following is e. specifics` tion. A This, invention provides cert-ein new end useful ineens for locking bolts securely in opplied position, end the object ci the inven tion is en iin roved bolt locking device which' is.V prevented) from being eccldentoliy displaced freni opel'etive osition, end which may be readily. removed to release the bolt when desired.

With this ond other objects in View es will more :fully appesi' es tlieciescription proceeds, the invention consists in certain constructions end errengements of posts that i. shell liei'einsitei" fully describe end tlieii point' claims.

.For e full understanding the invention end .the merits thereof, 4zeerenei-i is to be lied' to the oliowing description end accompanying drawinglinwhicli:
